Part of Perinton is under a boil water advisory today, after a water main break last night on Chipping Ridge.
The Monroe County Water Authority says this affects customers on Mosley Road including the side streets from Neuchatel Lane to Boxwood Lane and Garnsey Road.
The system lost pressure because of the break, posing the risk that microbes could be sucked into the system. The water authority says the boil water advisory will probably last another 24 hours.
Tap water should be brought to a rolling boil for two minutes and then allowed to cool before using.
